[0002] Rare earths are known as "industrial vitamins". Today, they have become an extremely important strategic resource. Rare earth elements have been widely used in the fields of petroleum, chemical industry, metallurgy, textile, ceramics, glass, permanent magnetic materials, etc. With the advancement of science and technology and the continuous breakthroughs in application technology, the value of rare earth oxides will become higher and higher. A large amount of water is required for certain blending during the mining and later processing of rare earths. The wastewater after cleaning the rare earths cannot be discharged directly due to the particularity of rare earths. It must be blended in a certain way and meet the discharge requirements before it can be discharged outdoors. Traditional rare earth wastewater treatment devices have poor treatment effects, cumbersome operation processes, and long treatment times.

[0003] Chinese invention patent CN107720846B discloses a wastewater treatment device for rare earth production, including legs, etc. A U-shaped treatment box is connected between the tops of the left and right legs, a water outlet pipe is connected to the bottom of the U-shaped treatment box, a valve is provided on the water outlet pipe, a fixed cover is provided on the top of the U-shaped treatment box, a water inlet is opened on the left side of the top of the fixed cover, and a spraying mechanism is installed on the top of the fixed cover.

[0004] The above patent has the following shortcomings: in order to increase the mixing effect of wastewater, a water pump is used to drive water to spray medicine in the mixing tank, and a motor is used to drive stirring to mix the liquid medicine. However, this setting not only introduces multiple new power sources, but also the medicine sprayed into the mixing tank cannot enter the bottom of the mixing tank at the first time. The sprayed medicine is in the upper layer of the mixing tank, which is not conducive to the mixing effect of the medicine and the volume optimization of the device.

[0005] Therefore, there is an urgent need to improve the processing equipment to solve the above-mentioned problems. Summary of the invention

[0041] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0042] like Figure 1-Figure 5As shown, the rare earth production wastewater treatment equipment provided in this embodiment includes a wastewater treatment equipment body 1 for rare earth production wastewater treatment, the wastewater treatment equipment body 1 includes a tank body 101, a tank cover 102 and a feed pipe 103, the tank cover 102 is fixedly installed on the top of the tank body 101 by multiple groups of bolts, the feed pipe 103 is fixedly connected to the bottom side of the tank body 101, and three supporting legs 104 distributed in a triangular shape are welded on the lower surface of the tank body 101. A valve is installed on the feed pipe 103. The back of the tank body 101 is fixedly connected with a wastewater feed pipe.

[0043] In this embodiment, if Figure 3 and Figure 4 As shown, a stirring device 2 extending into the tank body 101 is provided on the tank cover 102; the stirring device 2 includes a stirring shaft 201 penetrating the inside of the tank cover 102, a first stirring rod 202 welded and mounted on the outer surface of the stirring shaft 201, and a driving structure mounted on the upper surface of the tank cover 102 for driving the stirring shaft 201; the driving structure includes a driving motor 203 fixedly mounted on the upper surface of the tank cover 102, a first transmission gear 204 fixedly mounted on the output shaft of the driving motor 203, and a first driven gear 205 fixedly mounted on the outer surface of the top end of the stirring shaft 201 and meshing with the first transmission gear 204; wherein the driving motor 203 is a double-shaft motor, and a cavity 2010 and water outlets 2011 are provided inside the stirring shaft 201, and a number of water outlets 2011 are arranged equidistantly and communicated with the cavity 2010.

[0044] In order to improve the wastewater treatment effect, in this embodiment, Figure 1 , Figure 3-Figure 8 As shown, the wastewater treatment equipment body 1 is provided with a first spraying device 3 used in conjunction with the stirring device 2, and the first spraying device 3 includes a pump box 302, a medicine box 301 fixedly mounted on the side wall of the tank body 101, a water pipe 303 fixedly connected to the side away from the pump box 302 and respectively connected to the medicine box 301 and the stirring shaft 201, and a water conveying structure provided inside the pump box 302 for pumping water and connected to the driving structure; the tank cover 102 is provided with an abutment structure 308 used in conjunction with the driving structure to adjust the lifting and lowering of the stirring shaft 201. A positioning frame is welded on the upper surface of the tank cover 102 for fixing the driving motor 203 and the pump box 302.

[0045] Specifically, Figure 7As shown, the abutment structure 308 includes a mounting frame 3081 fixedly mounted on the upper surface of the tank cover 102, a first U-shaped frame 3082 hingedly mounted between the mounting frame 3081 and the stirring shaft 201, a second U-shaped frame 3083 hingedly mounted on the outside of the first U-shaped frame 3082, and an abutment wheel 3084 fixedly mounted on the top of the second U-shaped frame 3083. The driving structure is provided with an abutment bevel wheel 3085 abutting against the abutment wheel 3084, and the abutment bevel wheel 3085 is fixedly mounted on the outside of the spline shaft 2012. One end of the water pipe 303 away from the pump box 302 rotates and communicates with the spline shaft 2012. The spline shaft 2012 is hollow inside, and the upper and lower sides are connected.

[0046] It should be noted that a return spring is installed on the inner side of the stirring shaft 201 and the bottom end of the spline shaft 2012, which cooperates with the abutment structure 308 to make the stirring shaft 201 move up and down. When the medicine in the medicine box 301 enters the interior of the stirring shaft 201, the driving motor 203 is driven to rotate, so that the medicine can be evenly transported to the interior of the tank body 101, thereby enhancing the mixing effect of the medicine and the wastewater.

[0047] In order to achieve synchronization between stirring and conveying, Figure 5 As shown, the water delivery structure includes a second transmission gear 305 and a second driven gear 306 that are meshed with each other, a volume chamber 304 for rotationally meshing with the second transmission gear 305 and the second driven gear 306 is provided in the pump box 302, and the opposite ends of the two water delivery pipes 303 are connected to the volume chamber 304, and a synchronous shaft 307 connected to another output shaft of the drive motor 203 is fixedly connected to the second transmission gear 305, so that the water delivery structure is used to extract the liquid medicine in the medicine box 301 and inject water into the tank body 101 while the stirring shaft 201 rotates.

[0048] It can be understood that the water delivery structure has the same working principle as the gear pump. During the water absorption process, when the second transmission gear 305 rotates, the gear teeth gradually disengage to form an inter-tooth volume, which gradually increases, thereby sucking the liquid from one of the water delivery pipes 303. During the drainage process, as the second transmission gear 305 rotates, the gear teeth enter into meshing again, the inter-tooth volume gradually decreases, and the liquid is forced to be discharged from the other water delivery pipe 303. By unifying the driving of stirring and drug delivery, and providing power for stirring and water delivery at the same time through a single driving source, energy consumption can be reduced. Compared with two independent devices using their own motors or power sources, shared driving can more effectively utilize energy and reduce overall energy consumption. Since the stirring and water delivery actions are controlled by the same driving source, the coordination between the two is higher. In situations where precise control of the mixing ratio or flow rate is required, this design can ensure a high degree of synchronization between the stirring and water delivery processes, thereby improving product quality or the accuracy of experimental results.

[0049] In order to further improve the treatment effect of wastewater, in this embodiment, Figure 1 , Figure 2 , Fig. 9 and Fig.10 As shown, the upper surface of the tank cover 102 is provided with a second spraying device 4, which includes a connecting pipe 401 fixedly connected to the upper surface of the tank cover 102, a connecting shaft 402 rotatably mounted on the connecting pipe 401, a second stirring rod 403 fixedly connected to the bottom end of the connecting shaft 402 for stirring the liquid medicine inside the connecting pipe 401, and a feeding pipe 405 fixedly connected to the upper surface of the connecting pipe 401, and the connecting shaft 402 and the stirring shaft 201 and the feeding pipe 405 are respectively provided with a first synchronous structure 404 and a second synchronous structure 407. The first synchronous structure 404 is composed of two first synchronous wheels 4041 and a first synchronous belt 4042 that is transmission-connected between the two first synchronous wheels 4041, wherein the two first synchronous wheels 4041 are respectively fixedly mounted on the connecting shaft 402 and the stirring shaft 201, and when the stirring shaft 201 rotates, the second stirring rod 403 is stirred by the first synchronous structure 404 to stir the liquid medicine in the connecting pipe 401. The connecting shaft 402 rotates and extends into the connecting pipe 401 .

[0050] Specifically, Fig.10 As shown, the material delivery pipe 405 is composed of a hopper 4051 and a vertical pipe 4052 which are fixedly connected. The bottom end of the vertical pipe 4052 is fixedly connected to the upper surface of the connecting pipe 401 by bolts, and the hopper 4051 is in a cone shape. A material delivery member 406 is arranged in the material delivery pipe 405, and the material delivery member 406 includes a connecting shaft 4061 rotatably arranged in the hopper 4051 and a spiral conveying rod 4062 fixedly connected to the bottom end of the connecting shaft 4061 and extending into the vertical pipe 4052. The second synchronous structure 407 is composed of two second synchronous wheels 4072 and a second synchronous belt 4073. A shaft 4071 is welded to the top of the connecting shaft 402. The two second synchronous wheels 4072 are fixedly installed on the shaft 4071 and the top of the connecting shaft 4061 respectively. The second synchronous belt 4073 is transmission-connected to the two second synchronous wheels 4072. When the second stirring rod 403 rotates, the second synchronous structure 407 is utilized to make the feeding member 406 move synchronously, which can not only quantitatively convey the medicine, but also be used in combination to mix the medicine.

[0051] A limit frame is fixedly installed on the inner side of the hopper 4051 to limit the connection shaft 4061, so that it can rotate stably. The material is further stirred and conveyed by the rotation of the spiral conveying rod 4062. This double stirring mechanism can significantly improve the uniformity and efficiency of stirring and ensure that the material is fully mixed during the stirring process.

[0052] Another technical problem to be solved by the present invention is to provide a method for using a rare earth production wastewater treatment device, comprising the following steps:

[0053] 1) When it is necessary to treat the wastewater generated during the production of rare earths, first close the feed pipe 103 and add a certain amount of wastewater into the tank body 101 from the water inlet;

[0054] 2) Then, the first stirring rod 202 is rotated by driving the motor 203, the first transmission gear 204 and the first driven gear 205, and the liquid medicine in the medicine box 301 is extracted by the water delivery structure to inject water into the tank body 101. At this time, the medicine in the medicine box 301 enters the material delivery structure 308 for mixing and is delivered to the cavity 2010. As the stirring shaft 201 rotates, it is sprayed out, which helps to maintain the delivery of the medicine during the stirring process and promotes uniform mixing of the materials;

[0055] 3) Then, through the transmission cooperation of the first synchronous structure 404 and the second synchronous structure 407 , the liquid medicine added to the connecting pipe 401 can be fully mixed, so that the liquid medicine can more effectively treat the wastewater when entering the tank body 101 .

[0056] The wastewater treated by this method has better mixing, uniformity and energy efficiency than the current ones.

[0057] like Figure 1-Figure 10 As shown, the principles of the rare earth production wastewater treatment equipment and use method provided in this embodiment are as follows:

[0058] When in use, first, waste water is transported into the tank body 101, and then the first stirring rod 202 is rotated through the transmission cooperation of the driving motor 203, the first transmission gear 204 and the first driven gear 205. At this time, the synchronous shaft 307 drives the first transmission gear 204 to engage with the first driven gear 205, and the gear pump principle is used to extract the liquid medicine in the medicine box 301 to inject water into the tank body 101. As the stirring shaft 201 rotates, it is sprayed out. By using the abutment structure 3-8, the abutment bevel wheel 3085 is tilted and cooperates with the abutment wheel 3084 to realize the up and down movement of the stirring shaft 201, which helps to maintain the transportation of the medicine during the stirring process and promote the uniform mixing of the materials. It helps to maintain the transportation of the medicine during the stirring process and promote the uniform mixing of the materials. Then, through the transmission cooperation of the first synchronous structure 404 and the second synchronous structure 407, the liquid medicine added to the connecting pipe 401 can be fully mixed, so that the liquid medicine can more effectively treat the waste water when it enters the tank body 101.
